DIY: USB to VGA

Dianne Christensen-HermanUpdated February 21, 2017

Many graphics card manufacturers do not include analogue VGA monitor connections on their cards. Video/ graphics cards typically are equipped with digital DVI and HDMI connections, although some less-expensive options have VGA. If you have a VGA-only monitor that has a newer graphics card without a VGA connection, you may think the only option is to purchase a new monitor or downgrade the graphics card. However, there is a low-cost option to use a VGA monitor or television with a laptop computer that does not have a VGA connection. You will need to purchase a USB-to-VGA adaptor.

Push the VGA end of the adaptor cable into the USB port on the computer. Insert the other end of the cable in the jack on the back of the monitor or TV. The jack is usually located in the back of a TV or monitor and may be labelled with "S-video," but this could vary with TV models. Consult your owner's manual if necessary.

Finger-tighten the adaptor cable to the S-video jack on the TV or monitor until it is tight.

Power on the computer and monitor. A message should appear on the computer's screen stating the monitor or television has been recognised. The USB port has now been converted to VGA.

Press the "input" button on the remote until you see the computer's signal on the TV or monitor.

Tip

USB-to-VGA adaptors are in low demand and usually not available in walk-in electronics stores (see Resources). If you have an HDTV, you may need a VGA to component cable, because this cable acts as a converter.
